Doctors are going to perform more tests on Mandela, said Defense Minister Nosiviwe Noluthando Mapisa-Nquakula, who spoke to journalists outside 1 Military Hospital in Pretoria.

The office of President Jacob Zuma noted online that Monday is a special day because Mandela received the Nobel Peace Prize on December 10, 1993, for his "selfless contribution to the struggle for liberation, human rights and justice in South Africa."
